Cost of the Olympic Games
The Olympic Games are considered to be the world's foremost international sporting event with over 200 nations participating. It historically had the highest costs and expenses for the hosts, with the estimated cost of the 2016 Summer Games in Rio de Janeiro being at approximately US$11.1 billion.
Sports-related costs since 1960 have been on average US$5.2 billion for the Summer Games and US$393.1 million for the Winter Games. The highest recorded total cost was that of the 2014 Sochi Winter Olympics, costing approximately US$55 billion. The 2016 Rio de Janeiro Summer Games experienced the biggest loss recorded at approximately US$2 billion.
Host City Contract principles set by the International Olympic Committee require host cities, National Olympic Committees, and Organizing Committees to assume full financial responsibility for staging the Olympic Games. The contract also requires legally binding financial guarantees from host governments, making public authorities ultimately responsible for covering any financial shortfalls incurred by the Games.
